During the commissioning of the condenser cooling water system for the KoRi II power station in Korea, very turbulent flow conditions were observed in the stilling basin where the flow discharges from the main C.W. system. A 1-in-13 model was made to study the detail behavior of the flow in the siphons that connect the outlet culverts to the stilling basin. Several modifications, varying in their degree of structural changes to the original design, were examined with the intention of reducing the turbulent conditions at the siphon outlet. The model tests studied the flow patterns within the various siphon shapes, the flow losses, the priming times, and the behavior with air injected upstream of the siphon to simulate a free air-to-water concentration of up to 1% by volume. Extending the siphon outlet into the stilling basin by the addition of a roof positioned between the splitter wall and below the still water level proved to be very effective in reducing the flow conditions to more acceptable levels.
